Steel channels are broadly speaking C-shaped (or U-shaped) sections of steel, with a flat side and two flanges facing on to an open side.
Although the term ‘channel’ may sound like the section is intended to be used in a U-shaped configuration, for example to carry an open stream of water, in practice these are generally thought of as C-shaped sections.
This means that the ‘depth’ of the channel is actually given as the distance across the flat side, or between the flanges if they are parallel.
The ‘width’ of the section relates to the distance across the flange, from the corner where it attaches to the flat side of the channel, to its open opposite edge.
And certain other measurements – such as the thickness of the metal used – dictate the mass per metre of the section, which is typically quoted as its third dimension.
As such, a steel channel might range from ‘100 x 50 x 10’ – a closed side of 100mm, flanges of 50mm and a mass per metre of around 10kg – to ‘430 x 100 x 64’.
Note the different units used – whereas the first two dimensions are in mm, the third is in kg per metre.
Together, these should allow the desired size to be specified for any project with a good degree of accuracy. For more information about the supply of steel channels, contact James Dunkerley today.

Frequently Asked Questions (FAQs)
What are steel channels commonly used for?
Steel channels are widely used in construction for frameworks, supports, and reinforcements. They provide structural stability in buildings, bridges, and machinery. Their versatility makes them suitable for both heavy industrial projects and smaller residential applications.
How do C-shaped steel channels differ from other profiles?
C‑shaped steel channels feature a distinctive design that offers excellent load‑bearing strength while remaining lightweight. This shape makes them easier to handle and install compared to bulkier alternatives. They are often chosen for projects where both strength and efficiency are required.
Are steel channels suitable for outdoor projects?
Yes, steel channels can be used outdoors, provided they are treated or finished appropriately. Options such as galvanising or painting help protect the steel from corrosion and weather damage. When properly maintained, channels can perform reliably in outdoor environments for many years.
What industries benefit most from C-shaped steel channels?
C‑shaped steel channels are widely used across construction, manufacturing, and transport industries. Builders rely on them for frameworks and supports, while manufacturers use them in machinery and equipment. They are also common in vehicle chassis and trailers, where strength and reduced weight are both essential.
Do you offer additional services beyond supply?
Absolutely. In addition to supplying steel channels, we provide sawing, flame cutting, drilling, painting, and galvanising. These services allow us to deliver a complete solution, ensuring that your materials are ready for installation and long‑lasting in performance.
